Margaret's sarcophagus was originally placed to fit in the steps of the shrine of St. Edward the Confessor but moved at the time of the dissolution of the monasteries to the edge of the chapel. The step edging around the sides can however still be seen.

An annotated history of the Abbey in the Abbey's library states that the lid was removed in more modern times and the sarcophagus found to be empty. The monumental brass originally on the top of Margaret's tomb is long since missing, but the original wording around the edge and on the surface plaque was recorded historically.
